WILLIAM J. RPAMER, OF NEW YORK, N. 1.

GASOLENE-TRAP.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed November 14, 1907. Serial No. 402,115.

and State of New York, have invented a new and improved (last lene-'lr:u), of which the following is a full, clear, and exact descriptien.

This invention relates to certain improvements in traps adapted to be used'in connection with gasolene supply pipes or car bureters, and des gned to facilitate the separation of sediment, water, and other impurities in the gasolene before the latter is vaporized in the carbureter or engine.

The device is so constructed that solid impurities are strained out of the gasolene and collect at the bottom of a special chamber, the sides of which are transparent, so that the amount of water and sediment which has been collected may be readily ascertained and drawn oil through a stop-cock at the bottom.

Reference is to be had to the accompanying drawings, forming a part of this specifieation, in which similar charm-ters of refer ence indicate correspoiuling parts in all the figures, and in which Figure l is a side elevation of a trap constructed in accordance with my invention; Fig. 2 .is a central longitudinal section through the device shown inFig. 1; Fig. 3 is a transverse section on the line 3-3 of Fig. 1.; Fig. 4 is a perspectivr. view of the clip preferably employed for holding the screen in place, and Fig. Sis a detail showing in longitudinal section a modified form of means for securing the screen in place.

The trap includes in its construction, a body portion 10, adapted to be connected to an inlet. pipe it and an outlet pipe l2 or 12'. The inlet pipe is at. a lower level than the outlet pipe, and. the latter may either extend from the side of the body or from the top thereof, as is found most convenient in the use. if the outlet pipe 1; be employed, then a SLllt-ttbh. bracket or support may be threaded into the opening in place of the pipe 12 to support the body portion, while if the, pipe l2 is employed from the top of the body, then a suitable plug or bracket may be threaded into the opening in the side. The body is preferably formed of a casting of brass or other suitable metal, and is sub divided into a sediment chamber 13 and a puritied gasolene chamber 14, by a transverse screen 15. The screen is preferably of fine wire mesh secured in a frame which is removable from the body. The screen preferably engages with the under surface of a shoulder 16 and is held against downward movement by a spring clip 17 formed of wire and extending outward into a groove in the body just below the screen frame. One end 18 of the wire clip preferably extends downward. a short distance, whereby it may be engaged by a: suitable tool to remove it and permit the removal ofthe screen. The lower )ortion of the body is bored out to slightly larger diameter than the intermediate portion and is provided with two sight openings IS) in opposite sides thereof.

Disposed within the body and of a greater length than said sight openings, is a glass tube 30, the upper end of which engages with a packing 21 placed beneath the shoulder 22 in the body. The tube is of substantially the same diameter as the lower portion of the body, and is inserted in place through the lower open end of the body. A threaded plug 23 serves to close the lower end of the body and also to forces packing 24 against thelower end of the tube, the insertion of the plug also serving to force the tube against the upper packing 21. The plug carries a small pet-cock 25, whereby the contents of the body may be drawn otl' independently without necessitating the removal of the plug 23.

For, reventing the glass from being accidenta ly broken and to prevent the collection of dust and dirt upon theoutside thereof, so as to obscure the vision, 1 preferably provide a sleeve 26. inclosing the body 10 and having sight openings corresponding to the sight openings in said body. The sleeve is freely rotatable and is normally held so that the sight openings of the sleeve and the body are out of registry. When it is desired to examine the device to ascertain the amount of water or sediment collected in the body, the sleeve is readily rotated to bring the s ght openings into alinement. The screen 15 is, as previously stated, removable irom the lower end of the body, but other means than that illustrated in Figs. 2 and 1 may, if desired, be employed, as, for instance, that shown'in Fig. In this tigure,l have shown t;he frame of the screenilo beveled at its under side and held in place by two set screws 27, threaded tlu ough the walls of the ing with the beveled under surface of the frame. By inserting the set screws to their limiting position, the screen is forced-into firm engagement with the under side of the flange or seat 16. As shown, the screen is formed of reticulated metal, but, if desired, a piece of chamois skin may be substituted in place thereof, as the latter will serve equally well in preventing the passage of sediment and also of water, while permitting the free passage of gasolene.

In the use of my improved device, the pipe 11 is connected to the gasolene supply either adjacent the carbureter or at any suitable point in the supply conduit, and theoutlet pipe 12 or 12 from the device is connected to the carbureter. The inlet ipe being disposed beneath the screen de ivers the gaso ene, together with any impurities containedtherein to the chamber 13, m which all of the heavier impurities and the water settle to the i bottom. Any impurities which are lighter than the gasolene are separated by means of the screen, which also tends to prevent the momentum of the fluid from carrying along heavier lmpurltles.

The glass tube er'mits an inspection of the interior of the c amber to ascertain'when it is necessary to open the pet-cock 25 to draw off the impurities. If such a quantity of solid matter collects that it cannot readily pass through the pet-cock, the bottom plug 23 maybe removed. The spring clip 17 and the screen 15 may be removed from the under side Without removing the glass tube or afiecting the connections between the trap and the supply and discharge conduits. The glass is thoroughly protected on all sides, save at the sight open lngs, whereb the liability of injuring the same is great y reduced, if not eliminated.

Having thus described my invention, I
